Propagation of the electromagnetic wave through a chiral media can be explained by the following constitutive relations
that connect the complex displacement field \(\textbf {D}\)  and magnetic field \( \textbf {B}\)  [1]}, [2]}, [3]}, [4]}, [5]} as
\(\begin{bmatrix}{\bf D}\\ {\bf B} \end{bmatrix}=\begin{bmatrix} \varepsilon _0 \varepsilon & i \sqrt{\varepsilon _0 \mu _0} \, \kappa \\-i\sqrt{\varepsilon _0 \mu _0} \,\kappa &\mu _0 \mu \end{bmatrix} \begin{bmatrix}{\bf E} \\{\bf H}\end{bmatrix}, \)
